I use the Dillon one and have for several years, after retiring my old balance style measure. I like it, it is accurate and the numbers are easy to read, it balances quickly. I have had no problems so far with it and have been happy enough to recommend it. I have no experience with the other products, although they are all probably just as good, they come from good names that all stand by their products.
I like Dillon's no BS warranty, keeps me happy that I have the company stand by their products if anything ever happens, even if its my fault.
See if you can find a store that has most on display to play with them to help narrow your search further, after hearing what the other nutz have to say.
